Mississippi Cosmetology Board Practice Exam

Hydrogen bonds are weaker bonds that can be broken by water, making it the main type of bond broken during a wet set. Salt bonds are not typically present in hair and are not broken by water, so A is incorrect. Disulfide bonds are very strong and not easily broken by water, so B is also incorrect. Peptide bonds are found between amino acids in proteins, not hair, so D is not related to wet sets and is incorrect.
